What Makes Grammarly Stand Out
Unlike chatbot-style AI tools, Grammarly works where you already write. It integrates into browsers, email clients, word processors, and messaging apps. You don’t need to copy-paste text into a separate tool — corrections happen in real-time.

Professionals who write a lot of email and content and want automatic, real-time corrections. For content generation, use ChatGPT or Claude instead — Grammarly is about polishing what you’ve already written.
